The title of my blog explains itself. You can't tell everyone your goals and that's a sad reality but the truth, I talk about it in depth with this blog.
The reality of your journey is the closest people will not support you. It's a hard pill to swallow but it's better to hear it from someone who has experienced it than for you to realize it later on yourself.
Being jealous of others and their journey will get you nowhere. It only hinders your progress and what you should be doing...working toward accomplishing your goals.
